If DIY is not your strong point then fear not because our professional home installation service will do it all for you! The pro-install team will contact you soon after the delivery of your garden building to arrange a suitable time and date for the fitting.

A Firm and Level base must be in place and accessible before installation can take place - failure to provide this may incur additional costs. Pro-Installation does not include the fitting of any extra items such as locks or handles, and windows will be tacked into place only. Please view our Installation Page for full Terms and Conditions, which can be found here.

As standard cabin installation does not cover the installation of roof shingles. If you purchase a cabin with shingles and would like the shingles to be installed in addition to the building itself you must also add on the 'shingle installation' option at additional cost.

Unlike many budget competitor products our log cabins are built with only the highest quality materials and many log cabins in the market simply cannot compare!

  • SIGMA LOG CABINS feature high-grade 44mm interlocking planned and finished logs – beware of log cabins that feature rough edged boards machined from poor quality timber.
  • SIGMA LOG CABINS feature a specially designed 4-way chamfered notch-joint system ensuring a tight fit to all boards with little room for damp or wind penetration – beware of log cabins that feature square cut logs with square notch-joint, often leaving a sloppy joint with large visible gaps.
  • SIGMA LOG CABINS feature factory fitted pressure treated weatherproof heavy duty floor joists – beware of log cabins with untreated floor joists which offer no protection against damp penetration at floor level or worse still cabins that come with no floor joists at all.
  • SIGMA LOG CABINS feature heavy duty green mineral roofing felt as standard, with the easy option to upgrade to premium quality roof shingles – beware of log cabins that come with no roof covering, leaving the log cabin completely open to the elements.
  • SIGMA LOG CABINS feature oversized extra large doors and windows – most competitor log cabins use narrow doors which can prove difficult for access.
  • SIGMA LOG CABINS feature key-lockable opening windows and all doors and windows are professionally draft sealed – beware of cheap, ill-fitting doors and windows that cannot be properly secured and are susceptible to the weather.
  • SIGMA LOG CABINS feature high quality glazing which is factory silliconed and internally beaded to all doors and windows – beware of log cabins that feature lesser quality materials and provide no window beading.
  • SIGMA LOG CABINS feature a generous all round roof overhang which protects the building from severe conditions – beware of log cabins with little or no roof overhanging leaving them vulnerable to the wind and rain.

It is essential that our log cabins are assembled strictly in accordance with the instructions supplied on a firm and level base constructed from a suitably durable material. Our log cabins should also be treated as soon as is practical after assembly and then annually thereafter with an appropriate high quality preservative.

For more information on how to correctly assemble and maintain log cabins please consult our comprehensive help centre.

All images and photography of our log cabins are used purely for illustrative purposes only – actual product colours of the log cabins may vary slightly due to the digital photography process and variations in individual user monitor settings.

A great product at a great price. I am building six large houses at present and will recommend using Tiger Sheds to all my clients. Your installer Alan was extremely helpful and an absolute credit to you. 18/04/2018
Generally we are very happy with our log cabin purchase. The timber and machined finish of the logs is of excellent quality and we feel that we have had very good value for money. We were first attracted to owning a log cabin having seen a display of some at a nearby timber merchants. However, the price was off putting and so after looking on-line we came upon the Tiger sheds range. We were particularly impressed with the Sigma cabin and thought the quality of the windows and doors was superior to the finish we had seen with the competitor display ones. We found the website to be very clear and even though it was a bit risky ordering without seeing directly but we went for it and am well pleased that we did. We did have some relatively minor problems, though, and probably a 4 rating would have been fairer than the 5 given. Because of planning requirements we reluctantly opted for the reduced height version and found that some of the items provided (such as the facial boards) were for the standard height version so they requiredmodifying. However, these problems were overcome and we are well pleased with the final result. 21/10/2017

The cabin is very good quality and easy to build. We managed it over the May bank holiday with a couple of friends helping. Great outdoor space that we needed as the kids seem to have taken over the house. Thanks Tiger Sheds 14/07/2017

Great cabin had larger 30 ft by 20ft made - great value - all as agreed - had it erected by Tiger Sheds in a couple of days in the depths of winter! 20/05/2017

Very happy customer. I first started researching log cabins about 1 year ago. After a lengthy internet trawl I kept coming back to TS. The attraction for me was the 44mm log and the way it interlocked. Upon return to the UK I ordered up, the internet platform was great, options were easily followed, funds transferred and confirmation ped into your inbox as you expect. Plenty of notice when delivery was due. I've spent the last 4 days building the cabin with my wife and have enjoyed it tremendously. You have to get the foundations set and do need to get them level however, that goes for all construction projects so nothing new here. The material arrived well wrapped, well packed and in good order. The delivery driver gave me a quick run down on areas I may need to pay attention to, efficiently offloaded and headed off to his next job. Minor points of irritation, the way its packed on the pallet. The floor components are at the bottom so... you have to offload everything else to get to the first piece you need. I suppose you could say this is good as it allows you to familiarize yourself with the jigsaw pieces. The wood comes untreated so plan to have heavy duty plastic to lay the wood on and to cover it with otherwise it can take dirt and discolor. Forewarned is forearmed. The floor pieces go in well, take time with those and you are off and running. I'm no joiner but I was surprised how well things fitted together. The tiger shed team have made the shed so well there is limited room for amateur error. The one area that I would say does need work on.... the instructions are not good. They are all there but you end up squinting over an A4 piece of paper trying to count small lines with a small pen in fading light. To end on a high note as this product is extremely good value and extremely well made. If my garden was bigger I would order another, the joiners who are working on my garage extension want to start shipping them up to Scotland, the neighbours are nosing and my BMW GS1200 is looking forward to its new home. Thank-you to the team for taking the time to build a cracking log cabin and the support team for getting it up to me. A very happy customer. 24/11/2014

The cabin is well built and the men who constructed it were very good. My main criticism is that the builders left all their rubbish here the large pallet it came on (what am I meant to do with it) and all the packaging which took me 2 trips to the tip to get rid of. 31/10/2014
I had a larger size made [ 24x20] Nothing was too much trouble very pleased with customer service,delivered on time and as arranged. Delivery driver was brilliant, unloaded it exactly where we needed it. Extremely well packed with no damage to any parts, instructions seemed a little unclear at first but a thorough read thro' 2 or 3 times and we saw the light. Up and ready to use in 3 days. If I were to erect another one it would be a piece of cake.[2 Days I recon with 4 of us] 12/02/2013
